Cotton has been collected in Brazil for decades for its conservation, evaluation, and the use of its genetic resources. Gossypium mustelinum is an allotetraploid cotton species that only occurs in Brazil, and little is known about its genetic potential for improvement. However, the species is threatened by habitat fragmentation and interspecific hybridization with exotic species of cotton. In this study, we investigated the rate of natural hybridization in two populations of G. mustelinum in Bahia, Brazil, with G. hirsutum and G. barbadense using a set of microsatellite markers.
几十年来,巴西一直在收集棉花用于其遗传资源的保护、评估和利用。黄褐棉是一种异源四倍体棉花物种,仅在巴西有分布,人们对其改良的遗传潜力了解甚少。然而,该物种受到栖息地破碎化以及与外来棉花物种种间杂交的威胁。在本研究中,我们使用一组微卫星标记,调查了巴西巴伊亚州两个黄褐棉种群与陆地棉和海岛棉之间的自然杂交率。
